Description

Technical Field

[0001] This utility model relates to a spring plate self-resetting direction detection mechanism and an electric riding mobility device. Background Technology

[0002] Currently, electric riding mobile devices on the market, especially electric riding animal toys or amusement facilities, usually use buttons, pedals or remote controls to achieve basic start, stop and forward / backward control. This control method has the problems of limited operation and insufficient flexibility. In actual use, there are often response delays or limited operation, making it difficult to achieve natural and smooth directional changes and movement control, and failing to bring a real and immersive riding experience.

[0003] For example, CN119097930A discloses a powered wheeled riding device that relies entirely on differentiated force application from both feet to control the toy's movement. This device requires highly skilled operation when traversing terrain with many obstacles, and its emergency response is sluggish. For example, US20180272238A1 discloses an interactive riding toy device. This utility model attempts to simulate the interactive logic of pulling the reins to control the horse's head direction in real riding, but its forward / backward movement requires triggering via a separate button. This "button-triggered" operation lacks both the continuity of riding dynamics and a lack of immersion due to the fragmented operation steps. For example, CN219848117U discloses a biomimetic control riding toy. Although it simulates the control method of riding a horse, the steering smoothness is insufficient, and it cannot achieve turning on the spot or drifting, resulting in insufficient overall controllability and affecting the enjoyment of riding. For example, CN203186508U discloses an electric toy car with all controls on the steering wheel, and CN221138460U discloses a children's electric toy car. These two control methods require a high level of hand-eye coordination and cognitive ability. Young users may easily cause collision risks due to delayed operation or miscoordination in the face of sudden situations.

[0004] In addition, these products generally use a mechanical steering structure, which has a large turning radius, poor operational flexibility, and is difficult to use in confined spaces. Utility Model Content

[0014] This utility model also discloses an electric riding mobile device, including a frame, wheels, a main control board and a power supply. The wheels include a front wheel and a rear wheel, and also include the aforementioned spring plate self-resetting direction detection mechanism. The spring plate self-resetting direction detection mechanism is mounted on the frame via front and rear moving mounting blocks or mounting base plates. The front wheels and rear wheels are mounted at the bottom of the frame. At least two front wheels or two rear wheels are drive wheels, and the drive wheels are distributed on both sides of the frame. For example, two rear wheels are set as drive wheels and distributed on the left and right sides of the frame. There can be several or multiple rows of front wheels, and the number of rear wheels is not limited to two. There can be driven wheels other than drive wheels, or multiple rear wheels as drive wheels. The drive wheels on the same side move in unison.

[0020] This utility model also discloses a control method for an electric riding mobile device, which relies on the above-mentioned electric riding mobile device. When the push-pull steering rod is not under force, the left and right sensors and front and rear sensors of the spring plate self-reset direction detection mechanism do not detect the movement of the push-pull steering rod. At this time, no signal is generated and the drive wheel does not work. By manipulating the push-pull steering lever, the direction and speed of wheel rotation are controlled according to the action of pushing or pulling the steering lever. Specifically: Pushing or pulling the steering lever forward or backward causes the front and rear motion detection shafts to rotate. The front and rear sensors detect the rotation direction and angle of the front and rear motion detection shafts and send movement signals. After receiving the signals, the main controller controls the drive wheels to rotate forward or backward. Rotating the push-pull steering lever clockwise or counterclockwise causes it to rotate. The left and right sensors detect the direction and angle of rotation of the push-pull steering lever and send a steering signal. After receiving the signal, the main controller controls the speed difference and rotation direction between the drive wheels, thereby causing the electric riding mobile device to turn in the direction of rotation of the push-pull steering lever.

[0021] This utility model's spring plate self-resetting direction detection mechanism, through the cooperation of the push-pull steering rod and the front-to-back movement detection shaft with a sensor, can accurately capture the push-pull and left-to-right rotation movements of the handlebar. When applied to electric riding devices such as toy horses or amusement rides, the operator can control all movements and directions of the device through natural and intuitive handlebar operation, such as forward, backward, left turn, right turn, forward turn, backward turn, stationary rotation, and even drifting. The control is extremely natural, smooth, and fluid, greatly enhancing the riding experience. This utility model adopts a control method that is more in line with natural intuition, making the entire operation more in line with human instinct. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1 like Figure 1-2 As shown, this spring plate self-resetting direction detection mechanism includes a push-pull steering rod 1, a left and right steering reset plate 2, a left and right steering mounting block 3, a front and rear motion detection shaft 5, a front and rear motion reset plate 6, a front and rear motion mounting block, a front and rear sensor 12, and a left and right sensor 9. The push-pull steering rod 1 is rotatably installed in the left and right steering mounting blocks 3, and the left and right steering reset plates 2 are fixed in the left and right steering mounting blocks 3. The surface of the push-pull steering rod 1 is provided with a plane that abuts against the plane of the left and right steering reset plates 2.

The front and rear motion reset plate 6 will undergo elastic deformation, thereby generating a force to reset the front and rear motion detection shaft 5. When the external operating force on the push-pull steering lever 1 disappears, the front and rear motion detection shaft 5 can return to its initial state under the action of the reset force of the front and rear motion reset plate 6, thereby driving the push-pull steering lever 1 to return to its initial state.

[0025] When the push-pull steering lever 1 rotates, it squeezes the left and right steering reset plates 2, causing the left and right steering reset plates 2 to undergo elastic deformation, thereby generating a force to reset the push-pull steering lever 1.

The outer mounting block is sleeved on the inner mounting block and fixedly connected to the inner mounting block. The outer mounting block has through holes for the left and right steering reset plate 2 and the push-pull steering rod 1 to be inserted.

[0030] The left and right sensors 9 and the front and rear sensors 12 are angle sensors, and the system also includes a left and right sensor mounting block 10, a left and right sensor connecting block 11, a front and rear sensor mounting block 13, and a front and rear sensor connecting block 14. The left and right sensors 9 are mounted on the left and right sensor mounting block 10, which is fixed to the left and right steering mounting block 3. The center speed regulating shaft of the left and right sensors 9 is connected to one end of the push-pull steering rod 1 through the left and right sensor connecting block 11. The front and rear sensors 12 are mounted on the front and rear sensor mounting block 13, which is fixed to the front and rear motion mounting block. The center speed regulating shaft of the front and rear sensors 12 is connected to one end of the front and rear motion detection shaft 5 through the front and rear sensor connecting block 14.

The frame 200 has two front legs and two rear legs, which are respectively connected to the front wheels 300 and the rear wheels 400. The front wheels are either drive wheels or the rear wheels are drive wheels. The other wheels are universal driven wheels. The main controller 500 receives the signals emitted by the sensors of the spring plate self-resetting direction detection mechanism 100 and controls the rotation direction and speed of the drive wheels according to the signals, thereby controlling the movement state and direction of the electric riding mobile device. The battery 600 is used to power the device.

[0033] Alternatively, all four wheels can be selected as drive wheels.

[0034] The electric riding device also includes a protective support plate 700, which is mounted on the frame and located between the rider and the self-resetting direction detection mechanism.
